Thus, I have shown the screen I5 positioned on arelatively high point and facing toward the right of Figure 1, whereas Ihave shown the screen I4 somewhat lower than the screen I5 and facingtoward the front of Figure 1. 'I'he screen I5 in this way typies thescreen which would command an observation area in, for example, a publicroom, and the screen I4 may be said to represent a second screenarranged within a private office or the like;

In accordance with nw invention, a suitable source of light (not shown)is arranged within the projecting device I2 and is adapted to project'abeam i8 upwardly through the tape Il as the latter passes through thedevice I2.l Referring particularly to Figure 1, it will be seen that Ihave arranged an optical device in the form of a glass plate I1 arrangedin the path of the main beam I6 and at substantially 45 to the latter,

whereby the main beam I6 is split into two subordinate beams I l and,I9. The beam I8 passes I5 is directedin a lateral direction by thereflecting action of the glass plate Il.

It is obvious that the splitting of the beam in i v this manner 'willleave only a portion of the light ydirected toward a reflecting surface22, thence to a second reflecting surface 23, and projected `from thelatterlontothe rearA of the screen'V I5,

- which, in-this instance, would obviously be of a translucent characterso that the .markings 24 would appear on the front face of the screen asshowninFigure2.

The beam I5 is'directed towardand onto a reflector 25 and .thenceforwardly onto the rear of the screen Il, this screen also being of atranslucent character to render the markings 26 visible onthe frontkface thereof. r It is to `be noted.

that the markings 244 and are identicaland are produced on/,theirrespective screenssimultaneouslv. f

In Figure 4 I have illustrated/the possibility ofarranging a glass plate2l above a single objective lens 20' forrthegpurposeof fulfillingl thesame general object ina slightly different manner. It is to be notedthat the objective 20' is positioned in the main beam I5 prior to itsseparationinto the two subordinate beams. VA suitable reflector 25' isarranged in the path of the subordinate .beam 2l ina manner similar tothe arrangement of the reflector 25 in the path of the correspondingbeam I8 of Figure 1.

It is to be noted 4that the reflecting members are so arranged as tocreate direct and uninverted images on bothscr'eens Since one reflectionn would cause an inversion whereas two reflections,

or any even number of reflections, .would cause a rectification, it isobviousthat the two reflectors 22-and 2l accomplish the desired .objectlwith,` 'respect to the screen I5, whereas the reflector 25 in`conjunction with the refiectionof the glass plate I1, produces thedesiredeifect with respect Ato the screen I4.

yIt win thus beseen that 1l have provided a.

device which is extremely emcient yet exceptionl allysimplein structuralnature and'in'expensive from a manufacturing standpoint.l A singleticker and a single projecting device are employed. The markingsdisplayed on each of the screens are equally prompt with respect to thepassage of the tape through the projecting device I2. And the provisionof reflectors such as the members 22, 23, and 25, adjacent to respectivescreens, may be expeditiously provided for without resulting in anycumbersome or objectionable spaceoccupying structure. l

It will be obvious that the splitting of the beam may be accomplishedwithin the projecting device itself after passage through the tape. theforms illustrated serving merely to show the optical features of myinvention. For example,

. yifthe glass plate I'I .and one or more desired objective lenses .werearranged within the projecting device I2, then the two subordinate beamsmight be caused to emanate from two different openings in the projectingdevice itself. Similarly,.a suitable rearrangement of reflectingsurfaces will render it possible to project markings simultaneously uponlscreens positioned in diiIerent divergent and spaced manners from thosei1- lustratively shown.

In general.' it will be obvious thatl changes in the details hereindescribed and illustrated forI the purpose 'of explaining the nature ofmy invention may be made byk those skilled in the art 'without departingfrom 'the spirit and scope of the invention `as` .expressed in theappended claims. I tis therefore intended that these detailsbeinterpreted as illustrative. and not in a limiting sense.l f
